Islam Critiqued stuck with a problem; Abrahamic practices in Mecca?

In answer to the video "Abraham and the Kaaba: From Borrowed Stories to Sacred Scripture"

Even among the polytheist Arabs, like with the hanif previously mentionned, remnants of rites commemorating the Abrahamic legacy were maintained. For example, though they used to sacrifice animals on various idol altars at different places, their sacrificing of animals at Mina at the time of the pilgrimage was only in pursuance of the Abrahamic tradition. It was no sacrificing for any particular idols or their idols in general. Neither any idol nor any altar was there at Mina or Arafat. The ritual of sa'i or running between the two hills of Safa and Marwah is among God's signs. Just like foreign idols were brought to Mecca and integrated into the Kaaba, corrupting the Abrahamic legacy, some idols were placed on these hills. We read in the history books what caused this innovation. When 2 lovers named Assaf and Naila hid inside the Kaaba to be intimate, Allah turned them to stone statues. Associating this with a miracle, the Quraysh placed them each on one of the 2 hills, and as the generations passed, took them for deities.

The association of the site with paganism repulsed some early Muslims, but God told them plainly not to worry, for the Safa and Marwa are among His signs, regardless of how the sinful generations mishandled them

2:158-9"Surely the Safa and the Marwa are among the signs appointed by Allah...Surely those who conceal the clear proofs and the guidance that We revealed after We made it clear in the Book for men, these it is whom Allah shall curse, and those who curse shall curse them (too)".

The re-institution of this location as a monotheistic pilgrimage site comes in the context of patience in adversity and trust in Allah, just as Hagar was as she frantically searched for help, running back and forth between these 2 hills, when she was settled in the location by Abraham, together with her infant child Ismail. The practice of tawaf at the Kaaba, the circlings/circumambulations symbolizes the notion that all human endeavours ought to have the idea of God and His oneness for their centre.

Although the Quran itself does not require a specific number of circumambulations 2:125,22:26 the prophet used to circle the Kaaba 7 times and sometimes more. There is nothing special about the number seven in Islamic rituals and it doesnt even appear in the daily religious practices. It is only if one focuses on a certain number(s) that erroneous conclusions are drawn. The prophet repeated, and asked people to repeat certain things a variety of times, 1, 2, 3, 4, 5, 6 or even 20, all depending on appropriateness, common sense, educational or preaching purposes, or cultural understanding of his time.

The number seven entails a vast quantity in classical Arabic. This could have been the reason the prophet told his followers to repeat certain hajj rituals 7 times. With this notion in mind, the appropriateness of that number to certain hajj rituals becomes clear. Circling 7 times means that every possible thought and deed should have God at its center. Stoning the devil 7 times implies his casting away from every possible thought and deed. That is also why we refer to him in every day speak as well as in religious contexts, as 

"al shaytan alrajim/the pelted devil".

HE is pelted in thoughts and deeds through one's obedience to Allah. Pelting the stone walls during pilgrimage symbolizes this obedience to God, in contrast to disdain for the devil. With every stone that is disdainfully thrown, in contrast, a remembrance of Allah's greatness is uttered. The traditions speak of the devil appearing to Abraham as he was on his way to execute God's vision in regards to Ismail. Jibril instructed him to pelt the devil, who retreated then reappeared 3 times in total and every time Ibrahim listened to God's command to stone him. The pilgrims follow this example of Ibrahim, symbolizing their casting away of the devil by pelting 3 stone walls. Running 7 times between safa and marwa symbolizes trust in God despite the hardships of life, just as Hagar demonstrated in that same place, again, with the number 7 implying intensity of the trials of life, just as Hagar went through a difficult trial there.

As regards this number 7, what transpires from the HB Bible is that it is YHWH himself who attaches particular importance to that number, which was by the way, his day of rest following the difficult task of creating the world. In Josh6:1-8 prior to helping the Israelites with a miracle, YHWH insists that several deeds should be done 7 times precisely.

It is important noting, the Quran itself, throughout the verses laying out the hajj rituals 2:196,5:95-6,22:26-37etc doesnt link these rituals to Ibrahim, although it gives credit to Ibrahim for having initiated worship at the site and instaured the pilgrimage. This was part of the Quran's denationalization test of the Kaaba, placing it above any national pride, making its primary purpose to be a location where the one God is praised by all of humanity indiscriminately. These rituals should be done in God's name only. Every capable Muslim is bound to perform them at some point 3:97 with an upright state of mind before and during the journey 2:197.
